Buying rhythm

from 4 government buys since 2024

The government has bought this item about every 4 months (very regular, gaps vary ±29%). Last buy May 22, 2025. If the rhythm holds, the next one falls between Jul 27, 2025 and Dec 8, 2025: a buy is overdue by the usual rhythm.

How well this works: for very regular items, "next buy about one typical gap after the last, give or take 113 days" caught the actual next buy 48% of the time across 5,157 past buys, against 20% for a fixed "one year later" guess. A rhythm, not a schedule: DLA buys when stock and demand say so. Every item due for a buy now.
